Raised portal vein velocity
WebbAll cases of portal vein stenosis were caused by anastomotic strictures. The mean portal vein velocity at the anastomosis was 58 cm/s in patients with angiographically normal portal veins. The mean ratio of por- tal vein velocity at the anastomosis to the velocity before anastomosis was 1.5:1.
